Re: Do i have a vacuum leak on my headlamps?

I found my vacuum loss to be in the switch itself. The rubber block that slides over the vacuum ports had become hard with age. Along with the fact that the area where the block slides was not exactly flat. I followed Emma's post on taking the switch apart, and draw filed the uneven portion until it was truly flat. The rubber block was also made flat by sanding the block against a piece of sand paper on a flat surface. Additional pressure was added by putting a small piece of rubber in the "V" portion of the flat spring to press the block harder against vacuum ports. Some rubber lube also helped to provide more of a seal. My non-fail safe S2 will now keep the pods up for a little over 4 days after the engine is shut off.
